AnalogPortBench: Benchmarking LLMs on Analog Circuit Porting

Read the original on arXiv AI →

AnalogPortBench is a new benchmark comprising 54 tasks that evaluate how well large language models (LLMs) can port ten analog circuits—from current mirrors to telescopic amplifiers—across process nodes, specifically from a 0.18 µm process to the SKY130 PDK. The tasks vary in difficulty, ranging from straightforward ports to reduced supply and stricter specifications, and include infeasible scenarios; each feasible task has a verified reference design at five process corners. Experiments with six leading LLMs show that while models can handle simple circuit ports, they rarely redesign headroom‑sensitive amplifiers, often miss infeasible specifications, and benefit more from simulation feedback than from additional samples or reasoning steps.

AnalogScout: Simulation-Efficient PVT-Aware Analog Sizing with LLM Agents

AnalogScout is a new framework that uses a large language model (LLM) agent to perform PVT-aware analog device sizing more efficiently. By reusing elite designs, applying analytic gm/Id local sizing, and refining globally under full-corner verification, it cuts power consumption by 43.3% compared to the CMA-ES evolution strategy while using the same 16,000 simulations on three SKY130 OTAs. The method also outperforms Bayesian optimization and other LLM-driven flows on the tested OTAs.

PCBSchemaGen: Reward-Guided LLM Code Synthesis for Printed Circuit Boards (PCB) Schematic Design with Structured Verification

arXiv:2602. 00510v2 Announce Type: replace Abstract: Most LLM code-synthesis benchmarks rely on unit tests as the reward oracle, but PCB schematic design has none: correctness is defined by structured physical constraints over real IC packages and pin-level assignments, per-task golden references are unavailable, and SPICE simulation does not validate schematic-level correctness.

Green Code or Costly Code? Evaluating the Energy Costs of Iterative LLM-Based Code Optimizations

Large Language Models (LLMs) are increasingly used to optimize code for performance, but this study shows that such optimizations often increase energy consumption rather than reduce it. Across 11 open‑source models and 1,000 benchmark problems, inference energy ranged from 0.79 to 8.68 MJ, and 42 of 44 configurations produced code that used 4% to 886% more energy than human‑written reference solutions. Mixture‑of‑Experts architectures and token‑limit constraints can reduce inference energy, yet performance‑optimized code remains energy‑heavier, indicating that speed and sustainability are not always aligned goals.
